[Logged] is an interceptor-binding that you declare as the following:
```csharp
public LoggedAttribute: InterceptorBindingAttribute { }

To apply this interceptor, mark your class or methods with the interceptor-binding.

[Logged]
public class Foo
{
      /* all methods will be intercepted */
}

public class Bar
{
     [Logged]
     public virtual void DoSomething()
     {
           /* only this method will be intercepted */
     }
}
